Status, Command, and Alarm Propagation

Desigo CC has the capability to propagate the status of system objects in a specific view and allows the operators to use aggregators in that view to issue specific commands to the detectors belonging to a subtree at a lower level. For example, typically in fire applications, logical zones, which identify groups of detectors, can be included/excluded. This means that the operators can investigate the cause of a propagated status (for example, Propagated Mode = Included), and send pre-defined commands (for example, Exclude All) from the Operation/Extended Operation tabs or from the Status and Commands window.

You can configure the system objects properties that propagate their status information upward in that system view and the relevant commands to propagate downward along the view to command the specific points in a system subtree below. For instructions, see Configuring Status, Command, and Alarm Propagation.

The configuration of the status and command propagation depends on the object models. If a library does not include any object model, the configuration of the status and command propagation will not be permitted.

The command propagation depends on the view structure:

• Only objects in that view propagate their commands downward in that view while the command execution affects only objects from that level of the view down supporting that command.
• Objects that are not in the current view will not propagate their status and commands in that view.
• Objects belonging to views different from the one currently selected will not be affected by the commands issued from the current view.
